BALL-COCK VALVE.

SPECIFICATION forming part of Letters Patent No. 573,530, dated December 22, 1896- Application filed December 30, 1895. Serial No. 573,693. (No model.)

To all whom, t may concern:

Beit known that I, JOHN PoR'rEoUs, a citi zen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Ball-Cock Valves, of

vwhich the following is a specification.

My invention relates to what are known as ball-cock valves, and especially to such as are designed for use with flushing-tanks for water-closets. Its object is to provide a sensitive balanced valve-cock that will readily open by the lowering of the water-line in the tank and close noiselessly when the water has reached its upper level.

The invention will be first fully described in connection with the accompanying drawings, and then particularly referred to and pointed out in the claims.

Referring to the drawings, in which like parts are indicated by similar reference-letters wherever they occur throughout the various views, Figure l is a vertical sectional view of the valve in position in the flushingtank, the supply end of which is also shown in vertical section. In this View the Water is shown at its upper level and the valve in its closed position. Fig. 2 is a detailed view, in vertical section, of the valve-case, the valve being shown in longitudinal elevation and in the open position. Fig. 3 is a top plan view of the valve-case with the head and valves removed. Fig. 4 is a transverse section of the valve-case through line @c :c of Fig. 2 with the valves removed.

Referring to the parts by reference-letter, A represents a fiushing-tank of ordinary construction, in the bottom of which, near one end, is secured my ball-cock valve, the shell or case of which is represented by B. This case is divided into two chambers b and b by an S -shaped partition b2. Communication is formed between the chambers h and b by perforating the upper and middle horizontal walls of the partition, and the coinmunication between the two chambers is controlled by disk or piston valves c and c', which are formed integral with the shaft c2 and the ball-valve C, the upper face of which is recessed to receive the elastic packing-ring c3. The lower part of the valve-case is provided with an annular fiangel b3 to rest upon the bottom of the tank7 below which is the waterway 194, which passes through the bottom of the tank and is screw-threaded at its lower end to receive the cap-nut b5, by which the valve is secured in place in the usual manner.

The means shown for coupling the pipe leading from the main to the Waterway b4 (illustrated in the drawings) is well known and needs no specific description.

The head B' of the valve-case B has a tubular extension below a flange b, which is exteriorly screw-threaded to engage with the interior threads in the upper end of the case B. lVithin this extension is formed the downwardly-projecting annular ring bl, which fur- Y tends down to near the bottom of the tank,

so as to avoid noise or splashing when the valve is opened to supply water to the tank A. The upper end of the head B is a tubular neck, in which a plug c4 is fitted to slide, the

neck and plug being slotted to pass the arm i D of the operating-lever, which passes through the neck and plug c4 and is pivoted upon a pin d, which passes through lugs projecting from and formed integral with the tubular neck. rIhe portion of the arm D which passes through the slot in the plug cl is cam-shaped on both its upper and lower edges to avoid friction in operating the valve. The end of the arm D is perforated and tapped to receive its extension d', which is a rod, to the outer end of which is secured the float E.

The plug c4 and the valves are connected by a spindle F, which has screw.- threaded ends and annular flanges between the spindle properand the screw-threaded ends. One of the screw-threaded ends is screwed into the valve C, the flange above this end holding the elastic ring c3 in place. The upper flange of the spindle is made to snugly fit the neck of the head B', and between this flange and the plug c4 is an elastic packing-ring f, which is compressed betweenthe flange and lower edge of the plug to form a water-tight joint between the waterway and the plug c4.

The pistons or disks c and c are turned to slide freely through the perforations in the partition b2 and are guided by wings in the IOO usual manner. The pistons or disks c and c are arranged to cut on? the watersupply before the ball-valve C reaches its seat b. In practice I find it better to so arrange these pistons that they out olf the full supply when the ball-valve comes within about one-sixteenth of an inch of closing upon its seat. As the joints between the pistons or disks c and c are not absolutely water-tight, the further movement of the ball-Valve after said disks or pistons have reached. their seats will be very gradual, and no slamming or jarring or noise will occur by the final closing of the ball-valve upon its seat, and by means of the water-pressure when the pistons are closed or partially closed being between the pistons they are perfectly balanced and the valve will respond promptly to the movement of its actuating-lever either in opening or closing.

I have shown and described my ball-cock valve for use with an ordinary watercloset flushing-tank, but it is obvious that it may be with equal advantage applied to other uses, and it is also obvious that many mere mechanical changes may be made in the parts without departing from the spirit or scope of my invention.

l. In a ball-cock valve, the case divided into two chambers by a substantially S- shaped partition,the transverse walls of which have perforations which open communication between said chambers, united pistons controlling said openings, the valve connected to the piston-valves for controlling the exitopening in the case, a common stem for said pistons and exit-valve, and an actuating-lever to impart endwise movement to said stem to open or close all the valves, substantially as and for the purpose set forth.

2. The combination of the flushing-tank with the valve-case, divided into two chambers, having an inlet-opening to one chamber and an outlet-opening from the other, the partition dividing said chambers being perforated, piston-valves controlling communication between said chambers, an elastic valve V controlling the exit from said case, the said piston and elastic valve being connected, a stem having endwise movement in the case and common to all the valves, and a floatlever to open or close said valves by the fall or rise of the water-line in the tank, substantially as hereinbefore set forth.

3. The combination of the case inclosing two valve-chambers and having a removable head provided with a valve-seat surrounding the outlet from said case, said head having a neck above the outlet branch, piston-valves for controlling the openings between said chambers, an elastic Valve upon the stem of the piston-valve to control the discharge from the case, the stem for said valves extending past the discharge branch and into the neck, and provided with a suitable packing, and a lever actuated by a iioat. to impart endwise motion to said stem for the purpose of opening or closing` the valves, substantially as t hereinbefore set forth.

4. In a ball-cock lever, the combination of the case divided into two chambers by a substantially S-shaped partition, the transverse walls of said partition being perforated to open communication between the said chambers, an inlet to one of said chambers and an outlet from the opposite chamber, pistonvalves controlling the communication between said chambers, an elastic valve upon the same stem to control the outlet from the case, said valves being so arranged that the piston-valves cut off communication between the chambers before the elastic valve reaches its seat, a stem having endwise movement to simultaneously move said valves, and means such as shown for actuating said stem, substantially as shown and described.
